the first larval stage, when it appears as a tiny yellow object with six 

 legs which are atrophied before it reaches the adult stage. The male 

 and female larvtB are similar in the first stage, but later the male 

 acquires a pair of delicate wings and emerges from its scale covering 

 a free insect which never feeds, since its mouth-parts are replaced b}^ 

 extra pairs of eyes. 



The following short technical description with accompjun'ing illus- 

 tration (fig. 2) is appended for entomologists or persons who have 

 access to a compound microscope:
